fFW/M United States Patent @iiice 3,052,344 Patented Sept. 4, 1962 3,052,344 NUMISMATIC PROTECTEVE COIN HDLDER Charles Frank, 436 New Lots Ave., Brooklyn, N31. Filed Jan. 31 1962, er. No. 169,801 4 Ciairns. (1. 206--.82)

This invention relates to display receptacles, and more particularly to an improved numismatic coin holder.

A main object of the invention is to provide a novel and improved coin display receptacle for use in displaying rare coins, for example, by coin collectors, the receptacle being relatively simple in construction, being inexpensive to fabricate, and providing a means for clearly displaying a coin While completely protecting the coin against mechanical damage and from deteriorating elements.

A further object of the invention is to provide an improved coin display holder which is durable in construction, which is easy to assemble, which provides complete portection for a coin housed therein, which is neat in appearance, and which can be assembled and disassembled by simple manual operations without requiring the use of any hardware or tools.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

FIGURE 10 is a top plan view, similar to FIGURE 7, but showing the coin holder in locked condition.

FIGURE 11 is an enlarged cross sectional view taken substantially on the line 11--11 of FIGURE 10.

Referring to the drawings, the coin display holder is designated generally as 11 and comprises a first relatively fiat transparent body 12 in the form of a regular polygon for example, in the form of a square, the body 12 being centrally formed with a circular recess 13. Said body is formed at diametrically opposite portions of the recess 13 with the opposing arcuate lip elements 14, 14 which overlie the diametrically opposite adjacent marginal portions of the recess 13. As shown in FIGURE 3, the end edges 15 of the lip elements 14- are slightly beveled at their bottom portions, as shown at 16. As further shown in FIGURE 1, the end edges 15 of the opposing lip elements 14, 14- are substantially parallel to each other.

Designated at 18 is a second relatively flat transparent body identical in size and shape with the body 12 and formed with a lug 19 receivable in the recess 13, the lug having the straight parallel sides 211, 20 which are spaced slightly less than the spacing between the opposing straight edge portions 15, 15, the concentric arcuate end portions 22, 22 of the lug 19 having a diameter slightly less than the diameter of the recess 13. The lug 19 is formed with the opposing peripheral groove portions 23, 23 defining undercuts adjacent the arcuate edges 22, 22, and further defining the opposing arcuate locking projec tions or flanges 27, 27 shown in FIGURE 6. The lug 19 is formed centrally on the transparent body 18 so that when the body 18 is engaged with the body 12 in a manner presently to be described, the lug 19 is receivable in the recess 13 and the square bodies 12 and 18 are accurately superimposed with respect to each other and remain superimposed after the body 18 has been rotated through a quarter of a revolution with respect to the body 12 to lock the two segments of the coin holder together.

The inner face of the lug 19 is centrally formed with a circular recess 26 of sufiicient size to receive a coin 28 to be displayed.

The end edges of the flanges 27, 27 are preferably beveled, as shown at 29 in FIGURE 9, corresponding to the bevels 16 on the end edges of the lip members 14, 14.

Thus, the bevels 16 and 29 are approximately 45 inclined to the horizontal, as viewed in FIGURE 9.

The thickness of the lug 19 is almost exactly equal to the depth of the recess 13 and the flanges27 are designed to interlock with and cooperate with the lip members 14, 14 to scalingly interengage the end surface of lug 19 with the bottom wall of recess 13 when the members 12 and 18 are interlocked with each other.

In assembling the holder, the coin 28 is placed in the recess 26 and the lug 19 is then engaged in the recess 13 in the manner illustrated in FIGURE 7. Thereafter, the body 18 is rotated through one quarter of a revolution with respect to the body 12, whereby the flanges 27 lockingly engage under the flanges 14, 14 and cause the face of the lug 19 to be sealingly engaged with the bottom wall of recess 13, as above described, at the same time locking body 13 to body 12 in accurately superimposed relationship, as shown in FIGURE 10. With the parts locked together as above described, both faces of the coin 28 are clearly visible from opposite sides of the assembled holder 11, while at the same time the coin is completely scaled against the entry of moisture or other deteriorating elements, as well as being completely protected from mechanical damage. As shown in FIGURES 8 and 11, the holder has a rectangular cross section and is relatively fiat, making it easy to package and to store, and enabling a large number of holders to be stacked adjacent to each other or one above the other.

As will be readily apparent, when it is desired to remove the coin 28, the body member 18 is rotated one quarter of a turn with respect to the body member 12, whereby said body members are unlocked and may be disengaged from each other.

Instead of employing the bevels 16 and 29, illustrated in FIGURE 9, the opposing corner portions of the lip edges 15 and the flanges 27 may be rounded off with a suitable radius sufliciently large to facilitate the rotation of the leading edges of the flanges 27 pass the end edges 15 of the lip elements 14 when the body 18 is rotated relative to the body 12 to lock the components together.

While a specific embodiment of an improved coin display device has been disclosed in the foregoing description, it Will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claims.
